Hello,my name is Paolo, I would like to try to understand something about the usb audio interfaces.

I bought an XK-AUDIO-216-MC-AB card, I spent some days to read a bit of documentation and I would like to start testing if the card works.So I installed the evaluation drivers on the PC, powered the board (some LEDs lit up on the board) and I connected a USB 2.0 cable (I tried both jacks, first with micro then with type A) ... Problem: the pc does not see the usb device and does not install the drivers, there is no usb Audio device connected in the drivers control panelWhat is missing?

Hi, thanks for answer, but I have already tried to flash firmware on the board: i have built for example app_usb_aud_xk_216_mc_2i10o10xxxxxx.xe

During the downloading process: - the LEDs on xTag-3 blink and switch from red to green; - some LEDs on the Multichannel Board have switched off and then on; - on xTime Composer console, I see before some warning messages, then many "write" and "verified' messages, the last one is "Site 0 is done successfully".

However at the end of the process, my PC does not see the board as a USB device.I have also ligthed-off the board, detached xTag-3 and ligthed-on the board, nothing changed.

Well, I tried running the program with debugging, but I apologize, I do not know the program well, and not even xTime Composer, so I'm not sure I did it correctly: - I have connected the xTag-3 and board to the PC; then I switch-on the Board;- clicking on app_usb_aud_xk_216_mc_2i10o10xxxxxx.xe, with rigth button, I have chosed 'Debug as' and 'Debug configuration';- on main Tab i verified that Tharget was xTag-3, then I have cliked 'Debug'- xTime has switched to debug perspective, and, in Debugger tab, I see: - xCORE debugger - tile[0] core[0] (Running)CDTDebugModelPresentation.12=signal - tile[1] core[0] (Running)CDTDebugModelPresentation.12=signal - xgdb - C:\ .... \ app_usb_aud_xk_216_mc_2i10o10xxxxxx.xe

If I select xgdb line, in Console I see some messages, the lasts are: Start address 0x40000, load size 25507 Transfer rate: 177 KB/sec, 1594 bytes/write. info program Program stopped at 0x40000. It stopped with signal SIGTRAP, Trace/breakpoint trap. Type "info stack" or "info registers" for more information.
